Product formation in the reaction of Fischer carbene complexes with a metallophosphaalkene is dependent on the substitution pattern of the carbene ligand. With a methyl(ethoxy)carbene tungsten complex, the novel phosphaalkene 1 is generated as the result of a metathesis reaction. Alkenylcarbene complexes behave as Michael acceptors towards the metallophosphaalkene, whereas phenylethynylcarbene complexes undergo a formal insertion of the carbene unit into the P=C bond.
